SAFETY-EXTINGUISHER FOR LAMPS.

Specification of Letters Patent.

Patented Dec. 8, 1914;.

Application filed March 21, 1914. Serial No. 826,385.

To all whom it may concern Be it known that we, MELVIN E. Enron- SON andARTHUR W. MoonnN, citizens of the United States, residing at Grantsburg,in the county of Burnett and State of lVisconsin, have invented certainnew and useful Improvements in Safety-Extinguishers for Lamps, of whichthe followingis a specification.

This invention relates to new and useful improvements in safetyattachments for oil burning lamps.

The principal object of my invention is to provide a snuffer orextinguisher which will automatically operate to extinguish the flame ofthe lamp wick in case the lamp is tampered with or accidentallyoverturned.

A further object is to so construct the extinguishing device that itwill move into operative position immediately upon the dis placement ofthe lamp base from its normal position on the table or other supportingstructure, unless the lamp is to be moved from one place to another andthe person carrying the lamp holds the extinguisher in inoperativeposition by grasping a finger lug which is carried by the actuating rodof the extinguisher.

The above and additional objects are accomplished by such means as areillustrated in the accompanying drawings, described in the followingspecification, and then more particularly pointed out in the claimswhich are appended hereto and form a part of this application.

With. reference to the drawings, wherein there has been illustrated thepreferred embodiment of this invention as it is reduced to practice, andthroughout the several views of which similar reference numeralsdesignate corresponding parts, Figure l is a vertical section takenthrough a lamp equipped with our automatic safety extinguishing device;and Fig.2 is a detail perspective view showing the main elements of theextinguishing attachment.

Before taking up the description of the details of construction of ourinvention, it is desirable to explain that while the device has beenillustrated as applied to a particular form of oil burning lamp, andwill be hereinafter described in that connection, the principles of theinvention may be applied to any type of oil burning lamp by subjectingthe device to a few minor and obvious mechanical changes.

In the drawings, the numeral 10 dcsignates as an entirety the oilcontainer or body portion of a standard form of lamp. The container 10is carried in the usual manner on a hollow base or casing 11, having are duced upper terminal 12 of any suitable design. A burner, indicatedat 13, is threaded in the neck 14.- of the container 10 in the wellknown manner.

The extinguisher or snuffer consists preferably in a sheet metal sleeve15 which is mounted for sliding movement on the upper terminal of thewick tube 16, and is normally held in position below the exposed portionof the wick by means to be hereinafter described. As hereinbeforeexplained, the extinguishing device is so designed that it will operateautomatically to snuff out the flame of a wick l7 wheneverv the base 11is displaced from its normal position on a table or other supportingstructure. As a means for accomplishing this result, there is providedan actuating rod 18 which is riveted or otherwise secured at its upperterminal to the sleeve 15, as indicated at 19. This actuating rod 18 ismounted for sliding movement through a tube 20, which extends throughthe oil container 10 of the lamp, as clearly shown in Fig. 1. This tube20 extends diagonally through the container so that the lower terminalof the rod 18, indicated at 21, is considerably offset with respect tothe vertical center line of the base 11.

Arranged exteriorly of the base member is a cup-shaped member or pan 22,Wl11Cl1 1s also formed of sheet metal, and 1s preferably circular inshape, being of considerable area so that it will engage flatly againstthe top of a table, and will not be likely to mar or scratch the surfacethereof. Extending vertically from the member 22 and eccentrically withrespect thereto is an arm 23, which is pivotally connected to the lowerterminal of the actuating rod by means of a rock arm or lever 21 and alink rod 25.

The member 24- is pivotally connected at one terminal by a pin 26 to theupper terminal 0f the member 23, while its other terminal is pivotallyconnected by a pin 27 to the lower terminal of the member 25. As a meansfor supporting the member 2 1, there is provided a dependent arm 28which is secured at its upper terminal to a partitioning plate 29inserted in the lower end of the member 12. It will be seen uponreference to Fig. 1 that the member 2a is pivoted'ad= jacent itsterminal 27 to the lower end of the arm 28 by a pivot pin 30.

The link rod 25 extends through an opening 31 foi med in the threaded.at its upper terminal, whereby it mav be engaged with a coupling sleeve32, the upper end of which receives the terminal 21 of the actuating rod18. A set-screw 33 is threaded into the coupling sleeve, and engages themember 10 for holding it against withdrawal. The head of the set-screw33 is formed in the nature of a cylindrical ex tension, which serves asa fingergrip where by the operator may hold the extinguishing sleeve 15in inoperative position when the lamp is moved from one table toanother, as will be hereinafter fully explained.

From a central point of the member 22 extends a vertical sleeve 34:.This member 3 1 receives a vertical downwardly extending centering rod35, the upper terminal oi which is soldered or otherwise secured to themember 10, as indicated at 3 6. A helical spring, indicated at 37,surrounds the tubular sleeve 3%, and the rod 35, and has its upperterminal secured to the partitioning plate 29 and its lower terminalsecured to the outwardly extending flange 38, which is formed on thelower terminal of the member 3 1. This spring 37 is of the expansivetype, and normally serves to hold the pan 22 exteriorly of the hollowbase casing 11. I

The actual construction and arrangement of the several parts of thisinvention being thus described, it now remainsto explain the manner inwhich the sleeve 15 is automatically actuated to extinguish the flame ofthe lamp wick simultaneously with the displacemento i the base member 11"from its normal position on a table or other supporting structure onwhich the lamp has been placed.

Itwill be seen in lamp is placed on a table, the pan 22 lies in theplane of the lower edge of the base member 11, and that when the pan isin this position the terminal 27 of the member 2a is depressed to such apointthat thesleeve 15 is held with its upper edge below the. upper edgeof the wick tube 16 through the medium of the connectingrod 18. It willbe seen that the pan 22 will be projected beyond the confines or limitsof the base member 11 by means of the sleeve 37 in the event that thelamp is lifted from the table or is over-turned, causing the base to bedisplaced. The projection of the pan 22v from beyond the limits of thebase member 11 will, o1. course, swing the mem er as on its pivot 30,causing the member 25 p to move upwardly through the opening 31,resultantly-causing the sleeve 15 to be slid upwardly on the wick tube16 by meansoii the actuating or connecting rod 18. NVhen the sleeve 15isjthus slid upwardly on the member 16, it incases base rnember 11, andis Fig. 1 that when the the projecting terminal of the lamp wick, and,of course, extinguishes the flame by cutting oil the supplyof airnecessary to support combustion.

In case the user of the lamp wishes to move the lamp from one place'toanother without extinguishing the flame, the sleeve 15 'may be held ininoperative position by holding the member 37 with the fore-finger orthumb as may be most convenient. It will be obvious that should theperson carrying the lamp accidentally drop it, the sleeve 15 will beimmediately projected into operative position by the sleeve 37, and iurther that should a child unfamiliarwith the igniting device attempt toliitthe lamp from itsproper place, i will immediately move intooperativeposinot.

In reduction to practice, it has been found that the form of thisinvention illustrated in the drawings, and referred'toin the above theextin 'uishin" device description as the preferred embodiment, is

the most eflicient and practical; yet realiz ing that the conditionsconcurrent with the adoption of this device will necessarily vary, it isdesirable to emphasize the fact that Various minor changes in details ofconstruction, proportion and arrangement of parts may be resorted to,when required, without sacrificing any of the advantages of thisinvention, as defined in the appended claims.
